(GRANTED UNDER THE PRVISUNS @E THE .ACT 0F MARGH S, 1921, 41 STAT. L., 1313.)

To all who/m, t may concern.'

Be it known that I, RICHARD HENRY Itonicn'rs, a citizen of the Dominion of New Zealand, and residing at Farnley Tyas, Te Atatu Road, Henderson, Auckland, in the Provincial District of Auckland, New Zealand, a subject of the King of Great Britain and Ireland, have invented certain new and. useful Improvements in Timber- `work (tor which I have tiled application in New Zealand, No.42726, filed the 18th of November, l99, which matured into a patent the sealing date oii which is June 30, 1921), of which the following is a specification.

This invention relates to lattice work, and provides an improvement whereby a solid board, can be expanded to provide lattice work in the one piece, instead of lattice work constructed of separate pieces or battons secured together by tastenings. as is done at present,

According to the invention the board of suitable length and width is chosen, and lines are drawn across saine, one near each end.

Lines are also drawn across the board one on each side oi" the latters centre.

A. series ot parallel saw cuts are then made lengthways in the board, said cuts extending from the line near one end of the board to the line near the other end.

Other Vparallel saw cuts are then made from each end ot the board to the lines across saine near the centre thereof, each of said last mentioned saw cuts passing between two of the lirst mentioned saw cuts.

Owing 'to the saw cuts thus made, the board can then be expanded or extended to provide lattice work.

In the accompanying drawing Figure l illustrates a board with the saw cuts therein, and

Figure 2 shows the same board expanded.

A line l is drawn across the board near each end and lines 2 are drawnacross the board near the centre thereof and one at each side of the latter.

Parallel saw cuts 8 are then in the board said saw cuts 3 extending from the line l near one end oi the board to the line l near the other end of the board.

Further saw cuts l are then made between the saw cuts said saw cuts textending ii'oin each end ot the board to a line 2. Each saw cut Llis `located between two of the saw cuts 3.

rI`he saw cuts 3 and e made in the board in the manner above described, have the etiiect of making the board so pliant that it can be extended and expanded to forni latn tice work as shown in Figure 2.

rilhe saws used in doing this work are preferably held in sets orvgauges, and the gauge is first set in the saw bench so that when the board is dropped over the saws they will make the cuts 3, after which the cuts lare made from each end and between the cuts 3, to near the centre ot the board.

As a means of strengthening the lattice, the solid portions 5 at the ends of the saw cuts 3 and et, can be bound with wire 6 or hoop iron or the like, as a safeguard against splitting.

rllhe height oi the lattice can be as desired, and the series of cuts 3 and 4 can be repeated in the length of the board as often as is necessary.

This form ot lattice lends itself to being decorated by inserting ornamental parting pieces at the top and bottom and in the centre of openings, which pieces also strengthen the lattice.

rlhe thickness ot the lattice depends upon the use it is put to and if thick timber is employed the latter is steamed after the saw cuts have been made in order to facilitate the expansion ot the board.

By making lattice in the manner above dey the ends thereof whereby the board may be expanded to form lattice work, and reinforcing means wrapped about and completely embracing the solid portions of the board at the extremities of the cuts to reinforce the board at the bases of the lexures Vand thereby prevent splitting in any direction, said reinforced means being so dis-
